Hey, I am biased in that I now work with these guys, but Carsonified offers some great resources for people learning and improving their jQuery skill set.
Just next Monday there is an online conference on jQuery featuring John Resig himself - http://carsonified.com/online-conferences/jquery/
Also, they now offer video tutorials via their membership scheme on the Think Vitamin blog,
I know there's a lot of free resource out there, I guess the difference here is the quality of the content you get. hope it's useful!
